GANG Disk PLOW.

lApplication filed August 8, 1922. Serial No. 579,398.

To all who/m, t may concern.'

Be it known that I, STOKELY D. VVAL'roN, a citizen of the United States, residing at Imperial, in the rcounty of imperial and State. of'California, have invented certain new and useful Improvements in Gang Disk xvide a device of this character having. a

simplified means for coupling the beam to the ,main axle and relatively adjusting the same.

Another object of the invention is to provide a device `of this character having improved means for maintaining the cutting elements in lateral position.

Vith these vandother objects in view the invention consists in certain novel features ofl construction as-hereinafter shown and described and then specifically pointed out in the claims, and in the `drawings illustrative of the preferred embodiment of the invention:,

Figure 1 is a side elevation.

Fig 2 is a plan view.

Fig. 3 is a front elevation.

Fig. 4 is an enlarged side elevation of the adjustable brace members detached.

Fig. 5 is a sectional detail of one of the revolving disks. 4

Fior. 6 is an elevation of one of the disk clearing finger devices attached to the beam,

the latter being in transverse section.

. The improved device includes a main axle device 10 of any suitable kconstruction and having vertical elongated bearings -11 `atthe ends, and slidably disposed respectively in the bearings arestandards 12 and-12', the standard 12 supporting a bearing whe-e113 in itsvforked lower end. The standard 12 is outturned at itsl lower' end andterminates in an obliquely directed bearing for a guide whee113, the latter having an earth peneftrating -rib 132 and adapted to run in the nearest furrow. The standards 12 and 12 extend for a considerable distance above the.

bearings llland are each provided with a collar 14 at the upper end, the latter held in any suitable manner, for instance. by set collars 15, to prevent longitudinal` movement of the standards through the collarsy while leaving them free to rotate in the bearings. 1

Rigidly attached to each of the bearings l1 is an arm 16 having atoothed segment 17.l at one end and extending at the other end forwardly of the bearings, 4and each coupled `at its forwardly ext-ending ends to the collars 14 by springs 18.

Pivoted at .19 to each of the forwardly extended portions of the arms 16 is an operating lever 20, each lever connected by a link 21 to one of the collars 14, and provided respectivelyy with pawl devices 22 coacting with the teeth of the segments 17. By this means the standards 12 and 12 may be independentlyadjusted vertically through the bearings 11,- and held in adjusted position by the coaction of the levers 20, and

their attachments, to control .the verticaly position of the wheels 13 and 13.`

Connected at 23 to the axle device 10,is one section 24 of a pull bar, while another section 25 isv pivoted at 26 to the section 24.' 'A clevis device 27 is preferably coupled to the .forward end of the section 25 to receive the draft. appliance, not shown, but which maybe aL tractor, draft animals, or other power, as required.

Pivoted at 28 to the `section 25 of the pullv device is a rod 29, and rigidly connected .at 30 to the standards 12 isa bar 31, the rod being pivotally coupled to the bar as shown at 32.

By this arrangement the standard 12 and its obliquely supported guide wheel 13 is so coupledv to the swinging section 25, that.

any lateral movement of the draft appliance will rotate the standard 12 and cause the ance, the freely rotating wheel 13 correspondingly trailing the draft appliance, as will be obvious.

Pivoted at 33 to the axle member'10 is a relatively long heavy beam 34, the latter downturned at the rear end as shown at 35 and carrying a trailer wheel 36.

rlhe member 34 is preferably formed of a section of an I beam and provided witha A10o wheel 13 to trail afterfthe draft appliplurality kofl transverse apertures 37 at "brace member 46. f I y The brace members Aoverlap 'at theiry free .of cutting ldisks 40 are adjustably coupled tothe beam and adapted to be adj ustedboth vertically and rotativelyl vBy providing relatively large number of the apertures `e7, the disk cutters may be supported atV any required distance apart, or. any required number of the standardsl and disks 'employed, depending. on :the length of the beam and the number. of the apertures 37.

1F or the purpose of illustration 4 ysets ofthe apertures arey shown toreceive and support 4aofthe standards, but any number may be'` employe'dasrequired. It will be noted thata surplusl number of the 'holes are shownin the beam rearwardly of the rear cutting disk support, to show that an additional;Y nu-mber of the fdiskv supports may be employed if required. 7

Attac-hed at 41to .the beam `34 near` each of the standards :39, is a clearer device for each bf the disks 40k and comprising a plu,-

rality of fingers or spaced rods 42, -to pre-'i` vei'tzweedsfclods, and the like froinbeing carried over vthe disks;

vH ingreolly unitedat43 to the beam 34 near its rearl end is a brace member 44, and hing-v edly united at 45' tothe axle 10 another ends, 'and 'are each provided with aplurality oftransverse apertures 47 to receive clamp bolts 48, to provide for adjustably Acoupling wardly of the axle 10, "or' at richt vangles thereto, 'the' disks 40 will also ra'ilone behind 'the other,y but byshortening the distance between ythe hinge yconnections 43 and 45 ef the brace members 44 and 46 byy adjusting the bolts '4'.8 inthe 'apertures 47, the beam-34fmay 'be correspondingly adjusted togA `operate at an angle to the aXfleitO, `as shown iny EigzQ, and this angularity' may be in# creased or lvdecreased `to any desiredvextent withinthe'range yof the apertures 47 andthe lengths ofthebrace members 44 fand 46, Vas.

`will be obvious. f

' By this means the furrow produced by the coaction of the seriesof disks mayv be andmounted'to rotate freely on thev standards 39. yBv this means the force required 6,0.y-

action is more uniform. With the disks :arranged as shown and op increased or decreased as required.

, It will be 4noted that the disks 40`are arranged -to operate relatively near to a line parallel To the 'surface of the 'groui'idb' and are relativelyy shallow, las' shown in Fig. 5

to draw the udisks through the ground is materiatlly reduced while at 'the same erating nearly flatwis'e: to the ground,

`weights are-not required to hold the disks in time the the ground,but on the contrary the guide lWith the relatively smallv .vamountijof ,dishf i given to' the disks, they will clearl more readily `and Withrnaterially reduced` draft.
